1067：将 Class 类型的值隐式强制转换为不相关的类型 flash.data:SQLConnection

Question

我正在尝试使用此代码为我的本地 sqlite 数据库创建新记录 但它不起作用，当我点击保存时出现此错误

1120：Access of undefined property sqlConnection.

这是我在 EmployeeDAO 中的方法

          public static function  create(employee:Employee):void
    {

    var sql:String = "INSERT INTO words (id, term, defin, term1, defin1) " +
            "VALUES (?,?,?,?,?)";
        var stmt:SQLStatement = new SQLStatement();
        stmt.sqlConnection = sqlConnection;
        stmt.text = sql;

        stmt.parameters[1] = employee.term;
        stmt.parameters[2] = employee.defin;
        stmt.parameters[3] = employee.term1;
        stmt.execute();
        employee.loaded = false;
    }

add.mxml 我尝试将记录保存到数据库的位置

    import model.Employee;
    import model.EmployeeDAO;

        protected function onSave():void {

            var newEmployee:Employee = new Employee();
            newEmployee.term = term.text;
            newEmployee.defin = defin.text;
            newEmployee.term1 = term1.text;
            newEmployee.defin1 = defin1.text;
            EmployeeDAO.create(newEmployee);
            navigator.popView();
        }
    ]]>
</fx:Script>

<s:actionContent>
    <s:Button label="Save" click="onSave()"/>
</s:actionContent>

<s:layout>
    <s:VerticalLayout paddingLeft="10" paddingRight="10" paddingTop="10" paddingBottom="10"/>
</s:layout>

<s:Label text="term"/>
<s:TextInput id="term" width="100%"/>

<s:Label text="defin"/>
<s:TextArea id="defin" width="100%" height="200"/>

<s:Label text="term1"/>
<s:TextInput id="term1" width="100%"/>

<s:Label text="defin1"/>
<s:TextArea id="defin1" width="100%" height="200"/>

如果你想在不实例化类的情况下调用它，你应该将你的函数声明为静态的。然后就可以了

public static function  create(employee:Employee):void
